Spontaneous radial artery pseudoaneurysm in an infant due to idiopathic medial hypoplasia - a case report.

Spontaneous pseudoaneurysms are uncommon vascular lesions in children. A seven-month-old boy presented for management of a painless, pulsatile mass of the volar forearm identified as a pseudoaneurysm of the radial artery on imaging, definitively treated with surgical excision. Histology was concerning for fibromuscular dysplasia, without additional lesions on whole-body imaging.

Adventitial Cystic Disease of the Radial Artery.

Upper extremity adventitial cystic disease is rare, but the characteristic findings of this lesion should be known to the hand surgeon and used to guide treatment. We present a case of a young adult male who developed a painless mass in his distal forearm. Diagnostic imaging workup revealed a cystic mass that extended within and encased the radial artery.

Subtle radiographic findings of acute, isolated distal radioulnar joint dislocation.

Distal radioulnar dislocations typically occur in association with fractures of the distal radius and/or ulna. Rare isolated dislocations or subluxations are more difficult to diagnose and are initially missed in up to 50 % of cases. We present two cases of missed isolated volar rotatory dislocation of the distal radioulnar joint.

Current practice of microsurgery by members of the American Society for Surgery of the Hand.

Purpose: First, to determine the percentage of members of the American Society for Surgery of the Hand (ASSH) that use microsurgical techniques as part of their surgery practice, and second, to identify factors limiting their use of these techniques.

Methods: A 34-item, anonymous, Web-based survey was sent to all active ASSH members. Twelve items concerned demographics and 22 items addressed prior microsurgical training, current use of these techniques, factors currently limiting their use of these techniques, and potential methods to address these limiting factors.

Non-union of femoral neck fractures with osteonecrosis of the femoral head: treatment with combined free vascularized fibular grafting and subtrochanteric valgus osteotomy.

Femoral neck fractures, frequently complicated by non-union and femoral head osteonecrosis,present a difficult clinical situation, especially when young patients are concerned. Existing treatment options are valgus osteotomy to address the biomechanical factors or bone grafting to address the biologic factor. The authors describe the operative technique and results of combined subtrochanteric valgus osteotomy and free vascularized fibular grafting in management of five young patients with both non-union and avascular necrosis.
